The invention relates to a movable bed methanol to olefin arene spherical catalyst and a preparation method of the movable bed methanol to olefin arene spherical catalyst. The catalyst provided by the invention is prepared from the following components in percentage by weight: (1) 30 percent to 70 percent of a hydrogen type ZSM-5 molecular sieve; (2) 20 percent to 60 percent of binding agent oxide; (3) 0 to 10 percent of metal oxide, wherein a metal element is selected from at least one of La, Ce, Fe, Ni, V, Mo, Pt, Zn, Co and Ag; the catalyst is spherical; the sphericility degree is more than 90 percent, the grain diameter is 0.5mm to 4.0mm, the strength of the catalyst is 30N/grain to 80N/grain and the abrasion rate is smaller than 1 percent. According to the catalyst provided by the invention, the hydrogen type ZSM-5 molecular sieve, a binding agent and an auxiliary extruding agent are mixed; in a kneading process, an inorganic acid solution is added to peptize, and the mixture is extruded into a strip shape through a pore plate with a certain pore diameter; after pre-drying is carried out, the mixture is shaped into a spherical carrier with the size of 0.5mm to 4mm through a cutting machine and a shaping machine; 0 to 10 percent of the metal element is loaded on the carrier and modification is carried out to prepare a methanol to olefin arene spherical catalyst. The catalyst has the advantages of uniform pelletizing granularity, high strength, high yield and small loss, and can be applied to a methanol to olefin arene movable bed process.
